Clarence Seedorf said there is "a lot to do" if he is to hoist AC Milan back to the heights of European and domestic football after he arrived in Italy on Wednesday.

Dutch veteran Seedorf announced on Tuesday that he is to take over as coach of Milan, a day after the seven-time European champions sacked Massimiliano Allegri in the wake of a shock weekend loss to Serie A strugglers Sassuolo.

Seedorf, the first man to win the Champions League with three different clubs after stellar spells with Ajax, Real Madrid and Milan, has spent the past 18 months with Botafogo in Brazil.

The 37-year-old arrived at Milan's San Siro ground on Wednesday evening to meet the players in time to see a 3-1 Italian Cup win over La Spezia.

After Sunday's reverse, Milan sit 11th in the Serie A table, 30 points behind leaders Juventus and 20 behind Napoli, who occupy the third and last qualifying spot for the Champions League.

Seedorf, who was mobbed by waiting media at Milan's Linate airport after his flight from Brazil, told the in-house Milan Channel: "There's a lot to do to hoist Milan back to the top."

But he reassured the club's desperate fans by adding: "I can't really call this a comeback, because I never really went away."

As a Milan player Seedorf was a figurehead, making more than 400 appearances and winning the Serie A title twice as well as a pair of Champions League crowns.

The Surinam-born star had his first taste of European glory with Ajax in 1995, a second success with Real Madrid three years later and he then won club football's top prize with Milan in 2003 and 2007.

Seedorf, who added a Rio league crown to his CV last year, had been expected to prolong his stay in Brazil but was widely believed to have had a clause inserted into his Botafogo deal allowing him to leave for a top coaching post.

His performances in midfield helped Botafogo to qualify for the Copa Libertadores, the South American equivalent of Europe's Champions League, which starts on January 29, for the first time in 18 years.
